Google released two new accessibility features this week to its social network Google+ as part of its ongoing effort to allow disabled users more usability of its Hang Out feature.

The new Sign Language Interpreter app allows deaf or hard of hearing users to include their own interpreter inside a hangout. The interpreter's image will be shown in the top right corner of a Hangout window, and will automatically become the main image in the hangout whenever he or she speaks for a deaf user.

Also released is an updated set of keyboard shortcuts for better accessibility for those who might not be able to use the mouse during a hangout. Disabled users can mute their microphones by typing the Ctrl+D command on PC or Command+D on a Mac. To begin a chat, they can type Ctrl+B on PC or Command+B for Mac. A full list of shortcuts is accessible by typing "?" during a hangout in the chat window.
